But there is more: A third foundational fact in the Christian development of science and technologies was that the early and medieval Christians understood that God intended they apply the gift of reason to understanding and ordering the gift of Creation—for our flourishing. They saw this important role of reason in the cultural mandate already in Genesis—for example, in the task assigned to Adam and Eve of naming the animals, or God’s charge to them to cultivate and keep the garden.
That the medieval church was not afraid to exercise this mandate of applying reason to the world is illustrated in the story of the man who became pope just before the turn of the millennium – in 999 AD. Of humble origins, Gerbert of Aurillac – who was perhaps relieved to be able take the papal name Sylvester – had developed through talent and education into Christendom’s foremost mathematician. A teacher of arithmetic, astronomy, and harmonics, Gerbert’s knowledge in these fields was admittedly hampered by his inability to read Greek—and therefore to read the best of the ancient pioneers of those fields. But his career showed that even in those so-called “dark ages,” the study of natural philosophy (what we have called “science” only since 1834) was no impediment to a highly successful career in the church. And why should it be? For early and medieval Christians adapted that field of study, “natural philosophy,” from the Greek philosophers, only now understanding it as the study of God’s wisdom as reflected in his creation.
In fact, a couple of hundred years after Gerbert, another Christian scholar, Hugh of St. Victor, described the natural world as a book written by God’s finger – and therefore just as appropriate for Christians to study as the Bible.
For medieval natural philosophy to develop into science as we know it today, however, it needed two more understandings.
